GEORGE B. READ, OF BLOOMING-TON, ILLINOIS.

ELEVATOR.

Specification of Letters Patent.

Patented May 18, 1920.,

Application filed October 23, 1914. Serial No. 868,239.

T 0 all whom it may concern Be it known that I, GEORGE B. READ, a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Elevators, of which the following is a specification.

My invention relates to elevators and has special reference to elevators adapted for use in connection with grain handling upon the farm.

I aim, through my invention, toward simplification and greater adaptability of devices in this art than has heretofore attended those that have been placed upon the market; also toward reduction in first cost. For specific designation, would say that my object is to produce an elevator in sections and parts adapted for proper relative adjustment, union, and placement to fit in any kind of a warehouse, crib or granary, without the requirement of an especially skilled man in the art to accomplish such placement.

A further object of my invention is to provide driving connections for the conveyer in the elevator sections that will serve to drive the same from the head portion or upper extremity thereof to the end that there shall be no slack in the upwardly traveling portion of the conveyor element. Also my invention includes means for directing the conveyor element at varying angles as the elevator head and sections are moved to different relative angles.

My invention provides a factory-built machine that does not require from the pur chaser any specifications relative to his warehouse except as to height. I build an initial elevator section for vertical positioning that extends from the driveway floor line to a height above that of a farm wagon. I then provide plural sections in numbers to approximate the specified height, the same being joined to form a permanent section, but adjustable relatively to form a reach from the initial elevator section to the high point desired. I then hinge this section to the initial section so that it may be swung to the exact central point above the drive- .way (which driveway varies greatly in width in different houses), varying generally within the limits of 10 to 20 feet. I provide a head in connection with the swingable elevator section that is swingable with relation to said section so that the discharge opening therein may be disposed in horizontal plane, this provision of adjustment of the head being made to meet the condition of the swingable elevator section being disposed at different angles in different warehouses to accommodate the varying widths of driveways. I provide means for permanently fixing the sections of the movable portion of the stand together, and the movable stand permanently with relation to the initial stand and similarly, means for fixing the head in connection with the swingable stand, and I provide a pivoted drag or feeder of the well known type, to receive the contents of the wagon, adapted in practice to be of the vertical tilting or horizontal swinging type adapting it to be removed from the path of the wagon, and adapted to swing to and from the driveway floor. I of course provide suitable conveying means within the elevator thus built.

Referring to the drawings, a is a crib or warehouse, 5 refers to a diagrammatic disclosure of the dump.

Referring particularly to the associated elements constituting the elevator of my invention, 2 is an initial stand or elevator adapted to be positioned and supported upon the floor of a driveway and against the inner crib wall and extending upwardly some distance above the normal loaded wagon height; 3 is a drag or cross conveyer pivotally connected with the lower or booth portion of section 2 and is designed to be swung to and from the driveway floor to permit the wagon to be driven into dumping position and to receive the discharge therefrom when the latter is dumped. 4 refers generally to an extension section hinged as at 5 by means of strap or casting 6 secured to the upper end and at one side of stand 2 and fan shaped plate 7 secured to the lower end and at one side of extension section at. This plate is provided with a bolt opening as at 8 and through the medium of a common bolt the same is designed for attachment at different points in connection with the upper portion of the initial section, as for instance at points 10 and 11 in addition to the point of connection disclosed in the drawing. In practice, any number of adjusting points may be established as may be desired, to ac commodate a universal application of the device to enable it to swing to different angular positions to accommodate it for universal application. To establish a more stable connection between the initial and extension section, a plate or strap 12 is provided having a fixed connection with either of the said sections, and a similar provision of add1- tional connecting points, as for instance, 13 and 14C, to that provided in connection with plate 7.

The extension stand is adapted to be composed of plural sections as 15, 16, 17 or as many of said sections as may be necessary to meet the requirements of reach in placement and these sections are adapted for longitudinal adjustment relatively. However, in practice, I have only found it necessary to provide adjustment means in connection. with two of said sections, the additional sections being made in short lengths, more particularly for convenience of shipment and extension. To carr 7 out the adjusting function, I have provided oining points as at 18 both in the bottom and side walls of each section and by means of bolts or the like I am able to establish the normal jointed relation between the sections, and by the provision of supplemental perforations as 19 in the bottom side walls of one of the sections I am able to shorten or lengthen the reach of the complete extension stand 4:. While I have shown perforations for accom plishing this adjustment, this has in con templation any and all means that might be employed to fix or join the sections in their various relative adjustments.

A head section 20 is provided and having a ointed connection as at 21 with the upper end and at one side of the extension stand 4:. This'connection comprising plate or strap 22 and plate 23 and its component parts, is the same as the connection heretofore described for joining the initial and extension stands, and similarly in this connection I provide plural perforations as 24 to accommodate adjustment of the head relative to the extension stand in order to maintain the outlet portion 25 of said head in a horizontal position with the variance of angular position of the extension stand under various conditions of placement.

30 is a sprocket chain communicating motion from shaft 31 to shaft 5 and 32 is a sprocket chain communicating motion from shaft to shaft 33, the latter in the head of the elevator. This arrangement of drive is provided to cause the upwardly traveling portion of the conveyer elevator to be drawn taut, and without slack at all times.

in applying the device, the various parts are factory made and shipped in knock-down form, and in installing, the initial stand 2 is designed to be placed at one side of the driveway and suitably secured against the vertical inside wall of the crib or bin. The drag 3 is associated with the boot portion of said stand in a relation to permit it to swing up and down. The extension stand or section at is connected in a pivotal relation with the upper end of stand 2 and adjusted by relative extension of its sections to reach a point above the driveway so that the outlet 25 of head section 20 will stand approximately at the center of the driveway, said initial and extension stands being then fixed together relatively by and through the means hereinbefore described and similarly, the head section is adjusted and fixed with relation to the extension section in the manner hereinbefore described, and then by the attachment of the spout 26, the machine is in readiness for operation. The operation of the device after it is assembled being so apparent, it is not here set out in detail.

In applying my device I may vary from the details of construction herein disclosed, my purpose in the disclosure presented being to exemplify one form of embodiment of the invention, but it is not my desire to be limited to this particular form.
